This example displays a stylized smiley face constructed from basic SVG shapes, centered on a yellow circle outlined in black. The face is composed of three elliptical eyes and a curved mouth, all positioned symmetrically around the center. The code uses React to define reusable components, such as an `Eye` element, and leverages D3’s `arc` API to generate the mouth’s path geometry. The rendering is done via SVG within a 960x500 canvas, with all coordinates calculated from fixed constants.
